I have used FirefoxDriver but you can use any of the driver as per yourrequirement.
For selecting option from select box I have made instance of webElement and found select box using it’s id(“countryName”). By using webElement instance I fetched list of option that select box has by tagName. At last I have used for loop to get all value of list and checked option value equals to “INDIA” and if condition is true than I have clicked on that option.By this way INDIA will be selected in select box.
